First, you must accept Jesus Christ as your Savior (you accept Him as the Son of God). Second, you must find a way to read and to learn from the Bible (and if at all possible, pursue reading it multiple times as your remaining years unfold). Third, you must change your ways (or as the Apostle Paul would encourage you, 'to fight the good fight'). And once we understand that we are accountable to God – we can live as we learn from Philippeans 3:13-14
“But one thing I do: forgetting what lies behind and reaching forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus.”
(from it we will see if we can step up to these 20 challenges).
